"Abdiel was super to work with. He really knew his stuff and explained so many things to me that I did not know before. He gave me such a great deal that i couldn't say no. The system is perfect and the water delightful. Lucian installed the system. Couldn't have asked for anyone more gentlemanly. Very meticulous about his work. Seems to be a great company all around."

"Services were prompt, clean and efficient. Tech was knowledgeable and personable. Water heater was affordable. Estimate (free) was done on site - not guessing over the phone."

"Remodeling work cause leakages in the gas lines. I made an appointment with the scheduler BUT Michael Bonsby called me to understand the problem and to explain/assure me that they would ensure a thorough check on the gas line/safety. Mark the specialist spent a good couple hours going through every corner of the gas/water lines and sent me a written report. And he spent time explaining the technical aspects so now I know how to maintain the system. Strongly recommend them for service. Good value to price. Peace of mind!"

"I hired JC Flood to fix my hot water heater. They popped over for a quick appointment and our hot water heater worked for a few days before dying again. JC Flood explained the hot water needed to be replaced. They were excellent about including proposals for replacement units. Very much appreciated!"
